Abstract

The typical Xerox single pass highlight color printing system uses two separate color toner cartridges lined up near the photoreceptor. Referring to the figure, a toner carousel 10 has four toner cartridges 12,14,16, and 18. The toner cartridges can be removed separately to refill as needed. The brushes 20 of adjacent cartridges are located near each other and the adjacent brushes are parallel to the photoreceptor 22. This adjacent and parallel spacing of the brushes reduces the necessary length of the photoreceptor.

TWO PASS COLOR PRINTING USING TONER CAROUSEL(Cont'd)

The typical Xerox single pass highlight color printing system uses two separate color toner cartridges lined up near the photoreceptor.

Referring to the figure, a toner carousel 10 has four toner cartridges 12,14,16, and 18. The toner cartridges can be removed separately to refill as needed. The brushes 20 of adjacent cartridges are located near each other and the adjacent brushes are parallel to the photoreceptor 22. This adjacent and parallel spacing of the brushes reduces the necessary length of the photoreceptor.

The carousel is loaded into the xerographic printer as one unit. The selected toner color cartridge pair is rotated into position by one servo motor. The same motor used to drive the toner module can drive the selected brush pair. One rotation direction is used to select the color pair while the opposite direction is used to drive the brushes. A simple ratchet mechanism can accomplish this. Using tri-level exposure, two colors can be developed at a time. Thus, four colors can be developed in only two passes.
